Cancel caravan deployment

Just sent out a caravan and realized it will take 18h for it to reach its destination, because instead of -100 I sent it to 100 coordinate. Would be good to be able to cancel deployment of armies, caravans, etc.

I understand there is a messenger unit that can do this, but if you cancel the order within 2 minites of making it, you don't need to use such a unit.

Now I have to wait two days for my caravan to come back because of a typo...

I messed up my self because I accidently upgraded my padock instead of building a horse Cancling a second cued upgrade would Also be nice, but I support this one!
